C-arm X-ray Imaging Apparatus Sequence Mode Position Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray fluoroscopic imaging apparatuses face challenges in efficiently displaying the target rotation position information during sequence mode operations, leading to operator fatigue due to the need to scan multiple rotation positions on the monitor, making it difficult to quickly identify the current target position.
Innovation Solution
The apparatus includes a position information display element that shows the target rotation position in a fixed region, with adjacent display of the next rotation position, allowing the operator to easily understand the current and upcoming positions without constantly moving their gaze across the monitor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all rotation position information is displayed on the monitor during sequence mode operations, then the operator can see all available positions, but the operator experiences fatigue due to the need to scan multiple positions and has difficulty quickly identifying the current target position
Solution Approach 1:
The display is segmented into multiple regions: a first region displaying all rotation position information in the sequence, and a second region specifically displaying the current target rotation position. This segmentation allows the operator to see all positions while quickly identifying the target without scanning the entire display.
Solution Approach 2:
Different regions of the display are given different visual qualities - the first region shows all positions in a standard format, while the second region highlights the current target position with distinct visual characteristics (such as different color, size, or position), making it immediately recognizable without requiring the operator to scan the entire display.
2Loss of information
If the current target rotation position is highlighted in a different region, then the operator can easily identify it, but the operator still needs to move their gaze across the monitor to find the highlighted region
Solution Approach 1:
The solution moves the current target rotation position display to a fixed region that is spatially distinct from the general sequence display. By placing the target position in a separate, fixed location (such as a corner or sidebar region), the operator can monitor the target position in one part of the display while the sequence progresses in another part, eliminating the need to scan across the monitor.
3Ease of operation
If the display shows all sequence information in a fixed layout, then the information is easy to read, but the display cannot adapt when the sequence progresses to show updated target positions
Solution Approach 1:
The display system is made dynamic by automatically updating the second region with the current target rotation position as the sequence progresses. The control unit detects when the C-arm reaches each target position and automatically updates the display to show the next target, maintaining both readability and adaptability without requiring manual intervention.
